Watching the Time Trial

I'm off to watch the time trial tomorrow armed with a complete lack of local knowledge.
We're staying on Portsmouth road opposite the river and whilst this is on the route they will clearly be going past at ridiculous speeds so really want to watch on a corner for those added milliseconds of viewing Brad's lambchops.
Obviously also want to be on both the women's and men's routes.

Any thoughts on the on the Kingston Bridge area?

Alternatively it looks like there might be a big screen at Weston Green but I can't find many details. Anyone know anything?
